Polair split systems review: error codes, comparison of refrigeration equipment characteristics

The Polair group of companies is the leader on the Russian market for the production of refrigeration equipment with an annual turnover of about USD 150,000,000. The production capacity of the concern is more than 134,000 m² and are geographically located in more than 20 countries of the world.

From 1990 to the present day, the TM Polair manufacturing plant has been producing medium and low temperature refrigeration equipment for shops and catering establishments in accordance with environmental standards and European quality standards.

Main lines of air conditioners

The Polair split refrigeration system is a type of climatic equipment for maintaining a given temperature regime in the refrigerator. These devices consist of two main functional units: outdoor and indoor units, interconnected by copper pipes in thermal insulation and cable and wire products (power and operational circuits).

Refrigeration equipment classification from Polair

The company's activity is exclusively in the production of industrial air conditioners and refrigeration equipment. Domestic products Polair have high technical and economic performance, reliable performance and long service life.

According to the manufacturer's information, the products of TC Polair are represented by the following samples:

1. Monoblock systems (MM109S, MM111S, MM113S);
2. Backpack monoblocks with microchannel aluminum capacitor (ММ111R, MB214R, MB109R);
3. Ceiling monoblocks (MM109 ST, MM113 ST, MM115 ST);
4. Medium and low temperature split system Polair Standard (SM109S, SM222S, SM342S);
5. Split systems Professionale with coupling (SM109P, SB216P, SM115P);
6. Split systems with microchannel capacitor (SM111M, SB109M, SM115M);
7. Air coolers (AS201-1.5, AS202-2.8, AS311-4.5).

Split systems Polair Standard

Split systems Standard is an industrial refrigeration unit operating in low and medium temperature modes. The main functional unit of these devices is a powerful hermetic piston-type compressor, the production of which is carried out on the territory of the best European concerns for the production of compressor equipment.

Dry nitrogen (R 404) is used as a refrigerant in standard refrigeration equipment. Due to this, the temperature regime in the chamber can be in the range from -5⁰From (SM109S) to -18⁰C (SB331S). Condensate drainage from the system is carried out using a drainage 1 m long, which in the basic configuration comes with hermetically sealed soldering at both ends.

Split systems Polair Professionale

Split systems from the Polair company of this class are high-tech climatic equipment in which special couplings are used to connect the unit outlet with connecting pipes. Split systems Professional are supplied with modernized air coolers as standard, which increases the efficiency of the system by 30%.

Distinctive technical characteristics:

• Thanks to the use of special couplings, which contain a membrane that breaks only when the ends of the pipes and the outlet of the block are connected, a hermetically sealed cold loop of a closed type is obtained.
• When using modern diaphragm couplings for connecting functional units, the installation is carried out without errors.
• Choosing the Professionale series will allow you to get high-tech equipment of exclusively European production.

Split systems with microchannel condenser

Unlike the previous 2 split systems, these devices are equipped with a microchannel capacitor made of a special aluminum alloy as standard. Thanks to the use of this technology, the systems have the following technical characteristics:

Technical features of air conditioners with microchannel condenser:

• the dimensions of the heat exchanger are significantly reduced;
• the weight of the entire set is reduced;
• standard consumption of R404 refrigerant is reduced from 25 to 30%;
• the service life of the microchannel condenser is increased due to the inertness of the aluminum alloy to the water-air environment (does not corrode);
• Due to the smaller amount of refrigerant and, accordingly, the lower load of the compressor unit, the device's own energy consumption is significantly reduced.

Monoblocks

Monoblock Polaris - refrigeration equipment manufactured in accordance with GOST 23833-95 for operation in medium temperature (MM) and low temperature (MV) modes. These devices are capable of operating at ambient temperatures up to +40⁰C. In case of installation of climatic equipment of this version outdoors ("Winter set"), the ambient temperature should not fall below -10⁰FROM.

A distinctive feature of Polaris monoblocks is the optional ability to connect a remote control, which allows you to control the system from a distance.

Comparison table of characteristics of popular models

Let's analyze the main modifications of the Polair split system with the subsequent entry of the results into the table.

According to the table above, Polair low and medium temperature split refrigeration systems have high efficiency and low own energy consumption, which makes it possible to effectively use such systems in any industrial facility.

Polair control panel and air conditioners instructions

The remote control for the air conditioner (split systems) Polair is a portable device for refrigeration equipment. The installation of the device can be carried out at a distance of up to 10 m from the refrigerating chamber. According to the information provided, which contains instructions for air conditioners (passport) of this brand, the package includes:

• controller board;
• assembly and circuit diagrams;
• refrigeration unit operating instructions;
• Remote Control.

The main purpose of the buttons and the programming of the system are shown in the photo.

Also, the instruction for the equipment from the Polair company describes in detail how the air conditioner is installed and what difficulties there are during installation, the operating modes of refrigeration equipment, the schedule for maintenance and repair, as well as the frequency of cleaning the filters. In addition to the above, this document describes in detail the functioning of the device's self-diagnosis system, and also decodes the error codes.

Polair air conditioner error codes and malfunctions

Despite the fact that the company's split systems are highly reliable, sooner or later it will be necessary to carry out medium or major repairs.In the event of any malfunctions, the Polair diagnostic system will notify the service personnel using a special code, the decoding of which can be found below.

User reviews

Thanks to the Internet, you can find a huge number of resources on which owners of Polaris equipment have shared their opinions about the efficiency and reliability of TM Polair. All of them were systematized and summarized.

Positive reviews

• Relatively low price of split systems when compared to Zanotti and Technoblock.
• Convenient location of the condenser, which can be easily washed with Kercher.
• Reliable air cooler that does not rattle during operation with a high-quality fastening.
• Polair split-systems are equipped with French-made L ”unite compressors.
• Low power consumption.
• Connecting and repairing the air conditioner does not take much time and is easily carried out even by a non-specialized Polair team.
• Spare parts for air conditioning are easy to find in any market or in a specialized store with refrigeration equipment.
• Quick and easy setup of the system.

Negative reviews

• Bulky and unaesthetic air cooler housing.
• Unreliable magnetic starters that were installed on early models.
• When installing a monoblock on a camera, it is necessary to take a safety factor (about 30%), since otherwise the compressor will fail after 3 months.
• In the basic configuration, split systems are supplied without refrigerant.
• There is no remote control.

Based on the information presented above, the company's products have an ideal price-quality ratio and have good advantages for using the equipment of this particular manufacturer. If you need higher quality, performance and, accordingly, cost, then it is better to choose and buy imported equipment, such as Rivacold, Zanotti, or Technoblock, which are capable of cooling chambers with a volume of 650 cubic meters (SP marking).
